Once a block is written to the blockchain it can't be altered by anyone. If somebody tries to introduce a fake transaction into the ledger, he can only do so by adding it to all copies of distributed ledger (which is not possible, as every block is cryptographically linked with previous and next block) else that transaction is spotted and will be removed. Before a record is written to the blockchain, it needs to be verified and this is done by special nodes (computers) called miners.
